Abstract
Cor triatriatrum or divided left atrium presenting as mitral stenosis in an adult patient
Highlights
To our surprise, echocardiographic evaluation (Figs 1 and 2) revealed a primum ASD with the normal function of the left and right atrioventricular (AV) valve
A left-sided supra-valvular ridge or divided left atrium was identified with peak and mean gradients of 43/21 mmHg, respectively (Fig. 3)
Video 2 is an apical four-chamber of the post operative result
Summary
Echocardiographic evaluation (Figs 1 and 2) revealed a primum ASD with the normal function of the left and right atrioventricular (AV) valve. A left-sided supra-valvular ridge or divided left atrium was identified with peak and mean gradients of 43/21 mmHg, respectively (Fig. 3). Video 1 is an apical four-chamber view of the defect, pre-operatively.
